2. Whether the parts that affect the accuracy are within the allowable error. If it exceeds, adjust it appropriately.
3. Testing the accuracy of the instrument. Use a standard calibration device that is 3 to 5 times more accurate than the tested instrument to test its accuracy.
4. Security protection. If it exceeds 2%-10% of the upper limit of measurement, the instrument will stop automatically;
5. Appearance.

When the moving part reaches the limit, it should also stop automatically.
The carton inspection equipment industry has made a lot of achievements in research and development, production and supply, standard quality and other aspects, and has made great contributions. However, many problems have also appeared in the development process, and the industry will still need to pay on the road of future development. Work harder, overcome various difficulties, and continue to explore and move forward. As long as we look for the direction and clarify the goal, the overall development goal of the industry's prosperity and development will definitely be achieved.
